4.26.2.5.7 Module registers - Characteristic values (acyclic)
The following applies to all characteristic value module registers:
•
These registers are only available in Function model 2 - Slow master and Function model 254 - Bus con-
troller.
•
All calculated characteristic values can be locked using RequestDataLock01, which allows all registers to
be read in a consistent manner.
4.26.2.5.7.1 CrestFactorRaw01-04
Asynchronous register for reading the characteristic value "CrestFactorRaw" of the respective channel.
Since division by the RMS value takes place in the module ("RmsRaw"), there may be an overflow if the RMS value
is very small. To prevent this, the module has an internal lower limit of 1 mg for the RMS value.

4.26.2.5.7.2 FrequencyBand01-32
Asynchronous
register

band.
See
section
4.26.2.2.9 "Frequency bands" on page 2074.
If the frequency band parameter is set to a velocity signal, then this value is only calculated if the EnableVelocity-
Calculation bit (configured in the "SensorConfig01" register) for the respective channel is set; otherwise, 0 is output.

4.26.2.5.7.4 KurtosisRaw01-04
Asynchronous register for reading the characteristic value "KurtosisRaw" of the respective channel.
Since division by the RMS value takes place in the module ("RmsRaw"), there may be an overflow if the RMS value
is very small. To prevent this, the module has an internal lower limit of 1 mg for the RMS value.
